It is *possible* that I hadn’t cleaned ‘em out enough, it is *possible* that the cleaning solvents I used were the culprit, but I don’t think so.

Nowadays I use motor oil, and my shop-vac, unlike the fans I tried “fixing” with 3-in-1 for electric motors, still runs ( what’s with Shop Vac making their motors so damn difficult to maintain? )

It does smell aweful, though…

I simply don’t trust ‘em, now.

PB Blaster is the best thing for rusty parts just short of a torch. You’ll get rid of the WD-40 if you try the blaster on really bad rust.

I use Marvel MO….. but same general idea.

I like the aplicator on the 3-1

just like a zippo light fluid filler can,,,,, which by the way can be repurposed to apply any oil…..

I’m telling that one to the gf.

I was going to go with “Hot” but then I thought about all the different lubricants I have in the tickle trunk (My “assorted tools” box) between hoppes gun oil, Paintball marker oil, white lithium grease, and silicone spray. I use the WD40 for general crap, and this stuff just sits, like the redheaded stepchild of my lubricants. under the tap and die set…

Hot for table-top steam engines. Never gummed-up. does stink. I use it as cologne — attracts the right kind of girls. ;-D

Not. Generally speaking, multi-purpose often means no purpose. Remember when Hank Hill had a drawer especially for various adhesives? The same thought that you would put into an adhesive should be put into lubricants. Select your lubricants thoughtfully, as you would a fine single malt or wine. Only a Philistine would buy a grocery store lube.
